Patent JP-H02141967-A (JP)
Title: Waveform equalizer
Inventor: TANAKA HIDEKO
IPC: H03H15/00
Filed: 1988-11-21
Abstract: PURPOSE:To attain high speed setting processing with the less number of components by providing a variable voltage generating means, adjusting the level of a voltage inputted to a multiplier and setting an optional equalizing parameter. CONSTITUTION:A D/A converter 10 outputs an analog voltage corresponding to an n-bit command signal from a variable voltage generating means to set an equalizing parameter K. On the other hand, a reproduced waveform signal Vin is retarded by 2r seconds at a delay line 3 and the result is inputted to a terminal A of a differential amplifier 4. A multiplier 9 multiplies the signal Vin with the retarded signal, outputs the result with a multiple of K and the result is inputted to an inverting input terminal B of the amplifier 4. An output Vout of the amplifier 4 is a detailed input signal Vin and the signal Vout is optimized by setting the parameter K to the signal Vin. As a result, the strength of the thinning of the waveform signal Vin is controlled in response to the output voltage of the D/A converter 10, then the parameter K is set at a high speed with the less number of components.

Abstract: PURPOSE:To converge the deviation of a vehicle speed without the stability of a running vehicle being lost, in a duty control type constant speed control device, by providing such an arrangement that a basic duty value is compensated through integration by changing the speed of the vehicle in accordance with the difference between the duty value and an output duty value. CONSTITUTION:A control value for an actuator adapted adjust the opening degree of a throttle valve is subjected to on- and off-control at an output duty value D obtained from a control chart line having a predetermined inclination and indicating the conversion characteristic of the duty between the running vehicle speed Vn and the slip vehicle speed Vs, and the actual running vehicle speed Vn is made to approach a desired vehicle speed VM stored in a memory. In this arrangement, the difference DELTAD between a set duty value SD corresponding to a desired vehicle speed VM and the output duty value D is obtained. Further the control chart line is shifted in parallel at an integrating speed in accordance with the value of the difference DELTAD, and the set duty value SD is compensated through integration in the direction in which the set duty value SD approaches the output duty D. Thereby it is possible to converge the deviation of the vehicle speed at a practically sufficient speed.
